COUNTER REFRIGERATION.

Specification of Letters Patent.

Patented Mar. S, 192i.

Application filed .Tune 21, 1919. Serial No. 305,753.

To @Zlio/710m itmay concern C v Be it known that I, EMIL JAHNKE, a citizen of the United States, residing at Flint,

in the county of Genesee and State of Michigan, have invented new and useful Improvements in Counter Refrigeration, of which the following is a specification.

lfVhere counters are used in stores for the display of meats and other perishable products, and are provided with refrigerating pipes at the back thereof, it is inconvenient to gain access to the goods on display, and at the same time cold air is indifferently supplied to the goods.

One of the objects of my present invention is the provision of refrigerating means at the front of the counter and in such location that the refrigerating means does not interfere in any measure with a salesman reaching forwardly over the counter for the removal of any piece of meat or other piece of goods.

Another object of the invention is the provision in combination. with refrigerating means located as indicated, of means for supplying air to the vicinity of the refrigerating means, and other means for deflecting the air after it is cooled rearwardly over the perishable products.

Other objects and practical advantages of the invention will be fully understood from the following description and claims when the same are read in connection with the accompanying drawings, hereby made a part hereof, in which: I

Figure l is a perspective of a counter provided with the equipment constituting the best practical embodiment of my invention of which I am cognizant.

Fig. 2 is a transverse section of the same.

Figs. 3 and 4 are detail views of certain features of construction hereinafter specilically referred to.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

In putting my invention into effect, I prefer to employ a counter body l, and to superimpose upon the same a slab 2 of marble or of other material compatible with the purpose of my invention. The forward edge of the slab 2 is spaced rearwardly of the forward side of the counter body l for the accommodation of a trough 3 that extends longitudinally of the counter at the forward side thereof. Fixed with respect to and extending upwardly and rearwardly from the upper edge of the front wall of trough 3 is a detlector 4, preferably of glass, as shown.

Fixed with respect to the counter body l and the slab 2 is a transparent guard 5 of glass or other material suitable to its purpose.

Disposed in the trough 3 is a refrigerating coil 6, designed and adapted to be connected in the ordinary or any other approved manner with a source of refrigerating-agent supply, not shown.

Arranged transversely of the slab 2 and communicating at their forward ends with the rear portion of the trough 3, are air supply. pipes 7.

It will be readily apparent from the foregoing that no element of my improvements is arranged so as to interfere with ready access being gained to goods on the slab 2, and that my improvements do not diminish the display capacity of the counter or prevent a prospective purchaser from viewing the goods to advantage.

I would have it understood that the deflector 4 is preferably of glass or other transparent material, so that the same will not interfere with the view of the goods.

It will be understood that with the coil 6 supplied with refrigerating agent, and air supplied to the rear ends of the pipes 7, the air will pass through the pipes 7 and over the cooling coil 6 and then over -the meats on the slab 2, being directed rearwardly by the deflector 4. In Fig. 2 I show means 21 connected with and adapted to force air 'into and through the pipes 7 The construction herein illustrated and described is the best specific construction that I have as yet devised. I do not desire, however, to be understood as confining myself to the specific construction and relative arrangement of parts, inasmuch as in the future practice of my invention various changes in the form and relative arrangement of parts maybe made without involving departure from the scope of my invention as defined in my appended claims.

Having described my invention, what 'I claim andV desire to secure by Letters-Patent, is:

l. Means for the purpose described comprising a counter hgdy a slab superimposed thereon and spaced rearwardly from the forward side of the counter body, refrigerating means disposed in front of the slab, a trough containing said refrigerating means, a defiector overhanging the refrigerating means and the forward portion of the slab, an air conduit and means for forcing air through 5 the conduit and over the refrigerating means.

2. Means for the purpose described com- Yprising a counter, refrlgerating means at l the front ofthe top` of the counter, a den Hector overhanging the refrigerating means 10 and the forward portion of the counter, an p air conduit, and means for forcing air through the conduit and over the refrigerating means.

In testimony whereof I afIiX my signature. 15
